IUGHF62-35469-40 Circuit Protection

Circuit Breakers: IUGHF62-35469-40 Application Field and Working Principle

Circuit breakers are necessary safety devices that protect electrical systems and prevent fire and injury. They are designed to quickly detect an overload or short circuit in an electrical circuit and disconnect the circuit to prevent damage. The IUGHF62-35469-40 is a type of circuit breaker that is specifically designed for use in harsh environments and extremely hazardous areas.

Application

The IUGHF62-35469-40 circuit breaker is designed to provide protection in hazardous environments such as mines, chemical plants and other industrial areas where there is a risk of explosion or fire due to excessive heat, sparks or open flames. This type of breaker can be used for both residential and commercial applications and is especially suitable for use in areas with high dust content, such as grain silos. The breaker is also capable of interrupting a circuit at a rated voltage of 415 vols and at a maximum current of 25A. It is also rated for up to 16000A of short-circuit current.

Working Principle

The IUGHF62-35469-40 circuit breaker functions on the principle of thermal or electromagnetic operation. In thermal operation, the breaker uses a bimetallic strip that heats up when the current exceeds the rated value. This heats the strip enough to cause it to bend and trip the breaker. In electromagnetically operated circuit breakers, the mechanism instead uses an electromagnet to trip the breaker. An oversized current passing through the circuit magnetically operates the trip mechanism, causing the breaker to trip in a fraction of a second.

Safety Features

The IUGHF62-35469-40 circuit breaker has several safety features that make it an ideal choice for hazardous environments. It has an arc extinguishing chamber that helps to quickly extinguish any arcs that may form during operation. The breaker is also designed with double-break contacts which provide redundancy in case one of the contacts fails. The breaker also has an adjustable overload trip settings to provide protection in the event of an overload.

Conclusion

The IUGHF62-35469-40 circuit breaker is designed for use in hazardous areas and provides protection from electrical overloads and short circuits. The breaker functions on either thermal or electromagnetic principles and has several safety features such as a arc extinguishing chamber and double-break contacts. The breaker is capable of interrupting a circuit at a rated voltage of 415V and at a maximum current of 25A.
